Comment: Why a 7-day moving average? Wisconsin tends to have cyclical patterns in testing results, with low spots typically on Mondays (this may be due to lower testing on weekends)

Source: Minnesota’s safe learning plan is very direct, very precise, with scientific basis. Determined on a local level.

Definitions (corresponding / similar to MN plan):

  • 2wk: Two-week case total (most recent 14 days), rate per 10K of county population
  • 2wk10s: Approximate two-week case total, rate per 10K of 10-19 population
  • 2wk20s: Approximate two-week case total, rate per 10K of 20-29 population; since over 50% of students on campus are in early 20s
  • daily7: Daily new-case running average (average over 7 days)
  • posratedaily7 (as a percent): Daily positive-test rate, running average (average over 7 days)

and a set of SUGGESTED GUIDELINES based on the Minnesota reference:

Criteria 2wk Criteria 2wk20s Criteria daily7 Suggestion
> 25 > 30 urge extra caution
> 28 > 45* decreasing consider staying home and watching class recordings (rather than attending in-person) and visit online OH
> 28 > 45* steady to increasing strongly encouraged to stay home and watch class recordings (attend in-person only as absolutely needed) and visit online OH.
> 30 > 50 decreasing ’’ ’’ ’’
> 30 > 50 steady to increasing based on the cited criteria from Minnesota, safety of in-person classes no longer seems supportable

*adjusted to reflect a corresponding proportion of the top cut-off.

    • Starting with late May, after daily tests regularly above 6000
[1] "The number of  cumulative deaths, at a lag of 21 days, are approximately 0.7 times number of cumulative cases to the 0.69 power."
